Joint inferences from cytoplasmic DNA and fossil data provide evidence for glacial vicariance and contrasted post‐glacial dynamics in tamarack, a transcontinental conifer

Aim Tamarack ( Larix laricina ) is an early‐successional transcontinental boreal conifer occurring within the spruce‐fir dominated forest. The aim was to infer the species biogeographical history and to assess the putative genetic imprint left by interspecific competition during post‐glacial migration, using cytoplasmic DNA and fossil data. Location Forty‐five locations were sampled across the transcontinental range spanning the North American...
